Always state your full Windows version (e.g., WinXP SP3; WinXP 64-bit SP2; Vista SP1; Vista 64-bit SP2; Win7; Win7 64-bit) when posting in a forum or newsgroup. Please do so in your next reply.
What anti-virus application or security suite is installed and is your subscription current? What anti-spyware applications (other than Defender)? What third-party firewall (if any)?
Has a(another) Norton or McAfee application ever been installed on the computer (e.g., a free-trial version that came preinstalled when you bought it)?
You may encounter temporary connection-related errors [e.g., 0x80072EE2] when you use Windows Update or Microsoft Update to install updates

How do I reset Windows Update components?
[Ignore the APPLIES TO section if Win7; Access KB971058 via Internet Explorer (32-bit) only; Run the Fix It in DEFAULT and AGGRESSIVE modes, then reboot]
